Scientific notation is used to compress large numbers in smaller numbers. In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.For example: 1 x 10² is equivalent to 100
A googol in scientific notation is 1 x [tex]10^{100}[/tex]
The number of Earths needed have a total mass of 1 googol kilograms =
(1 x [tex]10^{100}[/tex]) ÷ (5.972 ×[tex]10^{24}[/tex])
(1 ÷ 5.972) x ([tex]10^{100 - 24}[/tex])
0.16745 x [tex]10^{76}[/tex]
= 1.67 x [tex]10^{75}[/tex]
